By 1922 radio was changing from an avocation of experimenters and techno-geeks to something everyone wanted to have in their homes. The availability of commercially made complete radio receiving sets (or systems) made the changeover possible. Here RCA does its part to make radio something everyone wants. Compare the cover shown here with the back cover of the Sears radio catalog from about this time. This book, Radio Enters the Home, has been reprinted for collectors.
